Abstract: 目的 建立测定板山岗颗粒中(R,S)-告依春含量的高效液相色谱(HPLC)法.方法 色谱柱为Kromasil 100-5 C18柱(250 mm×4.6 mm,5μm),流动相为甲醇-水(12:88,V/V),流速为1.0 mL/min,检测波长为244 nm,柱温为30℃,进样量为10μL.结果 (R,S)-告依春进样量在0.04~0.32μg范围内与峰面积积分值线性关系良好;精密度、稳定性、重复性试验的RSD值均小于2%;平均加样回收率为97.96%,RSD为1.63%(n=9).结论 该方法操作简便、准确,精密度、稳定性、重复性均良好,可用于板山岗颗粒中(R,S)-告依春含量的测定.
